I already run a fully-functional e-commerce website and now I want it packaged as a Progressive Web App so I can distribute it easily and even publish it on Google Play through a Trusted Web Activity. Your main goal is to turn the existing store into a smooth, installable PWA while making sure product-tracking works flawlessly from cart to delivery. Key elements I need built in: • Push notifications configured through Firebase (or a comparable service) for order updates and promotions. • Reliable offline browsing powered by service-worker caching so customers can keep shopping when their connection drops. • The standard “Add to Home Screen” installation prompt on supported browsers. • A lightweight buyer-to-buyer chat module; sellers are not part of the conversation flow. • An enhanced feedback system that encourages verified purchasers to leave ratings and comments. • Accurate real-time order-tracking visible on each user’s account page. Once everything is in place, package the PWA for Play Store submission, passing all Lighthouse audits and Play Policy checks. Sit-down testing on a range of Android devices is required; if anything fails install, works slowly, or breaks offline, we’ll iterate until it’s ready. Deliverables: 1. Source code and documentation for the PWA, including service-worker scripts and manifest.json. 2. Firebase (or chosen service) setup files and keys handed over securely. 3. Buyer-chat and feedback modules fully integrated with the existing back-end. 4. Signed Android release bundle (TWA) ready for Play Console upload. 5. Step-by-step deployment guide so I can maintain and update the app in the future. If this sounds straightforward for you—especially the combination of PWA best practices, chat, and Play-Store packaging—let’s get started.
